It's pretty simple. The System.Net.WebClient types DownloadData method provides an easy way to get any data from a url:
Public Function GetWebPage(ByVal szURL As String) As String
Dim wc As New System.Net.WebClient()
Dim b() As Byte
Try
b = wc.DownloadData(szURL)
Catch ex As Exception
Return String.Format("Exception Occurred:{0}{1}", _
Environment.NewLine, ex.Message)
End Try
Return System.Text.Encoding.UTF8.GetString(b)
End Function
Hope this helps,
